Nesting tree selection in urban Woodpigeon; applications in urban planning to reduce the conflicts with human activities
Eduardo Gil, Anika Meyer, Diego VillanúaAbstract:
The urban populations of Woodpigeon (Columba palumbus) is
increasing throughout Europe, generating conflicts with humans associated with
damage resulting from their feces deposition or with their role in the
maintenance of zoonotic diseases. Despite this, the species has a significant
conservation value, as it is an important part of the diet of various
threatened raptors like the Bonelli´s (Aquila fasciata) and Iberian
Imperial Eagle (Aquila adalberti). Also, it is a game species whose
hunting generates large income in certain regions. In the present work, we assessed
the habitat selection during the nesting period, analyzing the tree species
used for nesting and nest distribution patterns in streets and urban
parks. It has been verified how the location of the nest is not random,
with a percentage of them in evergreen trees significantly higher than expected
and with a significant selection of certain tree species like Pinus sp.,
Robinia pseudoacacia or Ulmus sp …) while
others like Prunus sp., Melia azedarach or Populus
sp were avoided. Significant differences were also found in the
density of nests, being significantly greater in the streets (12.3 ±11.6
nest/ha) than in parks (5.7 ±3.7 nest/ha). It is discussed
how the plantations in areas with benches or vehicle parking of tree
species negatively selected by Woodpigeons for nesting and tree species
positively selected by Woodpigeons in the rest of the park areas might lead to
a reduction of the species associated conflicts while guaranteeing its conservation.
